Title: Sodium-sulfur battery
Inventor: SUGIMOTO KOJI
IPC: H01M10/39
Filed: 1988-03-01
Abstract: PURPOSE:To suppress the reduction of the electric resistance of an anode pipe and suppress the reduction of the battery energy efficiency by decreasing the diameter of wicks on the outer periphery wall side of the anode pipe and increasing the diameters of wicks located outside these wicks and wicks in an anode container so that sodium is kept in contact with the outer wall of the anode pipe for a long time. CONSTITUTION:The diameter D1 of wicks 8a on the outer periphery wall side of an anode pipe 6 is made small, diameters D2 and D3 of wicks 8b located outside the wicks 8a and wicks 8c in an anode container 4 are made large. When the upper liquid level of the sodium in a solid electrolyte pipe 5 is lowered at the final state of a discharge, the outer periphery wall face of the anode pipe 6 is kept in contact with sodium for a long time by the infiltration effect of sodium due to the capillary phenomenon of the wicks 8a with a small diameter on the outer periphery wall side of the anode pipe 6. The increase of the electric resistance of the anode pipe is suppressed, thereby the reduction of the battery energy efficiency is prevented.

Filed: 1984-03-16
Abstract: PURPOSE:To improve distance resolution by molding a packing material of a mixture of thermosetting resin powder in a B stage state and powder of a filler by hot press and sticking this packing material on one surface of piezoelectric ceramic. CONSTITUTION:Epoxy resin at a stage B is crushed into powder, which is put in a metallic mold together with a filler, e.g. tungsten powder; and the mixture is pressed at hot temperature. The solid line in a figure indicates pressure and the broken line indicates the temperature of the metallic mold. Then, the heating temperature is held at about 165 deg.C and then the epoxy resin causes network reaction to cure. The heating is stopped 100min later and the pressure is held at 2,500kg/cm<2> to cool it naturally. When 94-96wt% tungsten powder is mixed with the resin powder, acoustic impedance ZB is 20X10<6>-27X10<6>kg/m<2>.sec and the packing material with a value extremely close to the acoustic impedance of a vibrator is obtained. Further, 2,500+ or -100kg/cm<2> pressure and 165+ or -10 deg.C metallic mold temperature are most preferable as to the relation between the press pressure and temperature.

Abstract: PURPOSE:To handle two lines as one line by resolving the delay difference between two lines to synchronize them in a data communication terminal equipment provided with an ISDN fundamental interface where two lines of channel type B are connected through routes having the delay difference. CONSTITUTION:The figure shows one terminal, and the opposite terminal has the same constitution, and each terminal is provided with a control part 22 as the ISDN fundamental interface which transmits and receives information through B1 and B2 channels(CH). In an output part 20, data passing first and second CHs are temporarily stored in buffer memories-(BM) 2001 and 2002, and synchronizing patterns(SP) are separated by separating circuits 2003 and 2004 and are compared by a comparing circuit 2005 to adjust the read start time of either BM, and the delay difference is corrected to synchronize them.

In an input part 21, SP is generated by an SP generating circuit 2015, and SP and input data are switched by switching circuits 2012 and 2013. Thus, two lines of 64KBPS can be used as one line of 128KBPS.
